Airflow Certification

October 2026 practice

Checked against Apache Airflow 3.3.2, the stable release dated 17 September 2026. New DAG files import from airflow.sdk. Dataset was renamed to Asset. @task is the default for Python. PythonOperator still runs, and it is the migration path from older DAGs.

These 75 questions are a Data For Dummies practice set for the 15 modules. They are not an Apache Software Foundation exam and they are not an Astronomer certification. A 70% line on this page is only this page's practice threshold. Where a question says schedule, that is the Airflow 3 argument. Asset is the current name for what older notes called a Dataset.
